Sean Combs is looking to settle down once and for all in 2010 after secretly reconciling with his longtime on/off ex KIM PORTER, according to new reports.
Sources tells the rap mogul has ended his romance with Cassie and plans to propose to Porter in the New Year.
The website reports Diddy has even bought a 12-carat diamond ring as he makes plans to ask the mother of his baby twins and 12-year-old son Christian to be his wife.
Combs recently told Playboy magazine that Porter wrecked his romance with Jennifer Lopez a decade ago - because he couldn't get his ex out of his mind.
And he also told the publication he only had one more big romance left in him, explaining, "I've only got one more in me. If I find somebody and it doesn't work, I'll be ruined forever... I only have one more lifeline."
Porter walked out on Diddy when she was pregnant with his twins in 2007 after learning the hip-hop star had cheated on her with a photographer, who fell pregnant.
